| Advanced fundus imaging for early detection of eye diseases New optical scanning techniques like optical coherent
tomography (OCT)
allow high resolution imaging of the depth structure of
the retina. The
goal of the project is to improve the ability for early
detection of eye
diseases and to diagnose their progress based on this new
imaging
techniques. The focus lies on glaucoma diseases. Methods
that provide
ophthalmologists new possibilities to judge image data
should be
developed. An example for such a method is an automated
segmentation and
thickness measurement of the nerve fiber layer.
Furthermore, the
outcomings of the image processing must be visualised in
an appropriate
manner. Within the collaboration of the ophthalmologic
department of the
university clinic Erlangen and the institute for pattern
recognition we
design new methods for image enhancement. The war OCT
data is denoised
an motion artifacts are corrected. The ophthalmologic
department brings
in its experience in the development and application of
new methods in
ophthalmology, particularly from the SFB 539. Together
with the
competence of the institute for pattern recognition in
medical image
processing this is an excellent base for the project.
